Set SNMP Configuration

About this task

Use the Simple Network Management Protocol (SNMP) to communicate with controllers and service platforms within the wireless network. SNMP is an application layer protocol that facilitates the exchange of management information to and from a managed device. SNMP enabled devices listen on port 162 (by default) for SNMP packets from the management server. SNMP uses read-only and read-write community strings as an authentication mechanism to monitor and configure supported devices. The read-only community string is used to gather statistics and configuration parameters from a supported wireless device. The read-write community string is used by a management server to set device parameters. SNMP is used to monitor a system's performance and other parameters.
SNMP version Encryption Authentication Default state
SNMPV1 No No Deactivated
SNMPV2 No No Activated
SNMPV3 Yes Yes Activated

To configure SNMP management access:


  1. Select the SNMP tab.
  2. Activate or deactivate SNMPV1, SNMPV2, or SNMPV3.
    Setting Description
    Enable SNMPV1 SNMP V1 exposes a device‘s management data so it can be managed remotely. Device data is exposed as variables that can be accessed and modified as text strings, with version 1 being the original implementation. SNMPV1 is activated by default.
    Enable SNMPV2 Select the checkbox to activate SNMPV2 support. SNMPV2 provides device management using a hierarchical set of variables. SNMPv2 uses Get, GetNext, and Set operations for data management. SNMPV2 is activated by default
    Enable SNMPV3 Select the checkbox to activate SNMPV3 support. SNMPV3 adds security and remote configuration capabilities to previous versions. The SNMPV3 architecture introduces the user-based security model (USM) for message security and the view-based access control model (VACM) for access control. The architecture supports the concurrent use of different security, access control, and message processing techniques. SNMPV3 is activated by default
  3. Set the SNMP V1/V2C Community String configuration.
    Select Add to include additional SNMP V1/V2C community strings. Select the icon to remove the SNMP community string.
    Field Description
    Community Define a public or private community designation. By default, SNMPV2 community strings on most devices are set to public for the read-only community string, and private for the read-write community string
    Access Control Set the access permission for each community string used by devices to retrieve or modify information. The available options are:
    • Read Only - Allows a remote device to retrieve information
    • Read-Write - Allows a remote device to modify settings
    IP SNMP ACL Set the IP SNMP ACL used along with community string. Use the drop-down list box to select an existing ACL
  4. Set the SNMPV3 Users configuration.
    Select Add to include additional SNMPV3 user configurations. Select the icon to remove the user configuration.
    Setting Description
    User Name Use the drop-down list box to define a user name. Options include snmpmanager, snmpoperator, or snmptrap
    Authentication Displays the authentication scheme used with the listed SNMPV3 user. The listed authentication scheme ensures only trusted and authorized users and devices can access the network
    Encryption Select to activate encryption
    Password Provide the user‘s password in the field provided. Select the icon to display the character string used in the password
  5. Select Save to update SNMP configuration.
